Common Questions

What is the Clearfield Production System?

Clearfield® is a crop production system combining specific herbicides and seeds from crop varieties that have been traditionally bred for herbicide tolerance and high yields.

The available Clearfield herbicide Altitude® FX 2 allows growers to customize weed control for pressures specific to their crops while maintaining sustainability in resistance management plans.

Are Clearfield wheat varieties Genetically Modified Organisms (GMO)?

No. All registered or soon-to-be registered Clearfield wheat varieties were developed using traditional plant breeding methods. Therefore, Clearfield crops are treated as non-GMO, conventional crops and are approved for export worldwide.

What are the benefits of the Clearfield Production System for Wheat?

When you grow Clearfield wheat, you get the power of herbicide-tolerant weed control, combined with the unsurpassed broad-spectrum weed control of herbicides such as Altitude® FX 2. There is no better way to grow clean wheat on any field in any rotation.

Clearfield wheat allows you to:
  • Grow wheat after any crop, including barley
  • Choose from certified varieties from Crop Production Services and Richardson Pioneer
  • Control Group 1-resistant grasses
  • Manage uncertain or heavy weed pressure situations
  • Control tough weeds such as Cleavers, Chickweed, Hemp-nettle, Buckwheat and Kochia – including Group 2 resistant kochia

What are the requirements to grow Clearfield varieties?

Beginning in the 2015 growing season, BASF has simplified the Clearfield Commitment process with a new evergreen Clearfield Commitment. By signing the new evergreen Clearfield Commitment growers will need to sign only once and will not be required to sign again in the future. Similar to previous years, growers must sign and have the Commitments submitted by July 7, 2017.

How do I control volunteer Clearfield wheat?

There are many options available to control volunteer Clearfield wheat, including tillage and herbicides. For herbicides, glyphosate is an important and cost-effective tool that will control volunteer Clearfield wheat. In-crop herbicide applications for pulse and oilseed crops include products like Odyssey® Ultra, Equinox® EC and Poast® Ultra.

What can be grown after using Clearfield herbicides for wheat?

After applying Altitude FX® 2, the following crops can all be safely seeded:

3 months after application
  • Winter Wheat
1 year after application
  • Canary seed
  • Canola

Overview of the Clearfield® Commitment for wheat.

The Clearfield Commitment, an agreement between the grower and BASF, is an important part of growing Clearfield wheat. Not only does it serve as a licence allowing the grower to access the benefits of the Clearfield trait, it also preserves the integrity of the Clearfield trait, delivering the same level of germination and vigour you’ve come to expect from the Clearfield system.

Details of the evergreen Clearfield Commitment for wheat.

Dedicated to improving its processes, BASF updated the Clearfield Commitment to an evergreen Commitment in 2015. That means growers who signed a Commitment in 2015, 2016 or 2017 will not be required to sign again. However, growers who did not purchase Clearfield wheat in the listed years will need to sign a Commitment for the 2018 season.

  • Sales period for Clearfield wheat and registered chemistry is October 1, 2018 – September 30, 2019
  • Deadline for submitting the Clearfield Commitment form is July 9, 2019
